Land use changes are an important anthropogenic perturbation that can cause soil degradation, but the impacts of land conversion from growing cereals to vegetables have received little attention. Using a combination of soil analyses from paired sites and data from farmer surveys, we found significant soil degradation in intensive vegetable cropping under paddy rice–oilseed rape rotation in southwestern China. This study may alert others to the potential land degradation in the subtropics.
